The Tiny Tap Tempo (Reverse) is a small external tap switch from Throne Room Pedals, the brand of Revival Engineering. You connect it to a pedal that has a tap input and tap the switch to set the tempo of that pedal's effect, such as delay or tremolo, instead of reaching down to tap the pedal itself. The Reverse version is the one built for BOSS and similar pedals: it uses a normally closed switch, the polarity those tap inputs expect1.
The maker describes it as "truly the tiniest tap in town," and it is offered with either one or two tap outputs in the same small enclosure, so a single unit can drive two tap-compatible pedals at once1.
What the Reverse switch is for
Most pedals with a tap input expect a normally open switch: the circuit closes only while you press. The standard Tiny Tap Tempo (Normal) covers that case. BOSS and some similar pedals instead require a normally closed switch, which is closed at rest and opens when pressed. That is the difference between the two versions, and it is why Throne Room sells them side by side1.
The Reverse version works as an external tap switch for any pedal with a tap input; the maker cites its own Throne Room Tremolo as an example1.
| Version | Switch type | Suits |
|---|---|---|
| Tiny Tap Tempo (Normal) | Normally open | Most pedals1 |
| Tiny Tap Tempo (Reverse) | Normally closed | BOSS or similar pedals1 |
A two-output reverse version, the Tiny Tap Tempo 2X (Reverse), carries the same normally closed switch with two tap outputs, and the maker calls its switch "the most solid tap switch you've ever stomped"2.

Beyond pedals: sustain and pro audio use
The maker states the Tiny Tap Tempo may also be used with other pro audio gear, or as a sustain pedal for most keyboards1. For a keyboard player, that makes the Reverse version a compact sustain pedal option, provided the keyboard expects a normally closed pedal, which is the polarity BOSS-style tap inputs share.
Versions and availability
The Tiny Tap Tempo line is described by the maker as its best selling Tiny pedals, now in even smaller enclosures than earlier versions3. The line covers four variants: standard and reverse, each in one-output and two-output forms, the two-output standard version being the Tiny Tap Tempo (Normal, 2 Outputs)34.
As of 25 October 2026, the maker's product pages list the Tiny Tap Tempo, the Reverse version, and the 2X Reverse version as sold out123.
Questions
What is the difference between a normal and reverse tap tempo switch?
The normal (standard) version of the Tiny Tap Tempo uses a normally open switch, which suits most pedals. The reverse version uses a normally closed switch, made for BOSS or similar pedals whose tap inputs require that polarity. Choosing the wrong polarity means the pedal will not read your taps correctly.
Will the Tiny Tap Tempo (Reverse) work with BOSS pedals?
Yes. Throne Room Pedals built the Reverse version specifically for BOSS or similar pedals requiring a normally closed switch. If your pedal's tap input expects a normally open switch instead, the standard Tiny Tap Tempo is the matching version.
Can the Tiny Tap Tempo be used as a keyboard sustain pedal?
Yes. The maker states it may also be used with other pro audio gear, or as a sustain pedal for most keyboards. That applies to both the standard and reverse versions.
Is the Throne Room Tiny Tap Tempo still available?
As of late October 2026, the maker's product pages list the Tiny Tap Tempo and its reverse and two-output versions as sold out. The current version uses smaller enclosures than the earlier Tiny pedals.
